Khashoggi was last seen entering the Saudi Consulate in Istanbul on Oct. 2. The Saudi government said the killing was carried out by rogue agents as part of an interrogation that went off track — an explanation that has been met with heavy skepticism by lawmakers on Capitol Hill.

The U.S. intelligence community has reportedly determined that the Saudi crown prince ordered the death of Khashoggi, who was a critic of the government, even as Trump has stopped short of echoing that view.

"It could very well be that the Crown Prince had knowledge of this tragic event — maybe he did and maybe he didn’t! That being said, we may never know all of the facts surrounding the murder of Mr. Jamal Khashoggi," Trump said in a statement last year.

Several Senate Democrats filed a bill late last month to force the Trump administration to issue a public report on Khashoggi's death. And the Senate passed a resolution late last year that named the Saudi crown prince as "responsible," in a significant break with the administration.
